- Dropped the necessity of defining an attribute array in the field output method in each field type class.
- Made it possible to define 'attributes' array in the property of the field type class as the 'value' kwy was overridden by the 'value' or 'default' key of the field definition array.
- Removed default values in repeatable field type of the demo plugin.
Changed the names of some methods of the field type classes to make them simpler.
Changed the scope of the $aFieldTypeSlugs property to public to make built-in field types registration use the property.
Done with reconstructing the hidden field type.
Removed unnecessary lines.
Fixed a bug in the repeater field script that the remove button remained even when only one field is remaining.
